Abstract Background Diazinon (DZN) causes serious liver damage in both humans and animals. In the present study, the hepatoprotective effects of Cynara scolymus L. leaf extract against DZN-induced liver injury were examined. Methods Forty male rats were divided into five groups. The control group received a normal diet. The DZN group received DZN only (25 mg/kg, po). The DZN + Syl group received DZN (25 mg/kg, po) and silymarin (Syl) (50 mg/kg, po). The DZN + Art group received DZN (25 mg/kg, po) and artichoke (Art) leaf extract (1500 mg/kg, po). The Art group received Art leaf extract only (1500 mg/kg, po). After 15 days, serum tumor necrosis factor α (TNF-α), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lipid profile, protein carbonyl content, serum and hepatic malondialdehyde (MDA), hepatic TNF-α gene expression, hepatic catalase (CAT), superoxide dismutase (SOD), and vitamin C (Vit C) were measured and histopathological examination was performed. Results DZN caused a significant elevation in serum ALP, AST, ALT, MDA, TNF-α, protein carbonyl, hepatic MDA, and TNF-α gene expression in the DZN group as opposed to the control group. Also, DZN led to the reduction of hepatic CAT, SOD, and Vit C in the DZN group relative to the control group. The administration of Art extract resulted in not only a significant reduction in serum ALP, AST, ALT, MDA, TNF-α, and protein carbonyl but also an improvement of liver histopathological changes and hepatic CAT and SOD activities as opposed to the DZN group. Conclusions This study confirmed that Art leaf extract has liver protective effects and causes downregulation of oxidative stress in acute DZN-induced liver injury in rats.

Introduction: Diclofenac (DIC), a phenylacetic acid compound which belongs to nonsteroidal anti-inflammatory drugs (NSAIDs), is generally used for the treatment of various diseases such as rheumatoid arthritis, ankylosing spondylitis, acute muscle pain conditions and osteoarthritis. Overdose of DIC can lead to renal injuries in both experimental animal and human. Our research was done to assess the protective role of silymarin on renal damage induced by DIC in rats. Methods: Thirty-two Wistar rats were assigned to four groups (n=8/group). Group 1 was control group; animals in group 2 were administrated DIC; Groups 3 and 4 administrated DIC plus silymarin with doses of 100 mg/kg and 200 mg/kg, orally (p.o), respectively. Various biochemical, molecular, and histological parameters were evaluated in serum and tissue homogenate. Results: In the second group, the levels of kidney catalase (CAT), vitamin C and superoxide dismutase (SOD) remarkably reduced (P < 0.05) relative to the control group. Also, urea, creatinine (Cr), malondialdehyde (MDA), serum tumor necrosis factor-α (TNF-α) and gene expression of TNF-α in this group were noticeably elevated (P < 0.05) relative to the control group. Treatment with silymarin caused a remarkable elevation (P < 0.05) in vitamin C, SOD, CAT and a remarkable reduction (P < 0.05) in the content of MDA, urea, Cr, TNF-α gene expression and serum TNF-α in comparison with second group. Histological injuries were also ameliorated by silymarin administration. Conclusion: The results confirm that silymarin has an ameliorative role against renal damage and oxidative stress induced by DIC in male rats.

Introduction: Diclofenac (DIC) is one of the compounds derived from acetic acid which isknown for its anti-inflammatory and analgesic attributes. Silymarin is a flavonoid compoundwhich is derivate from Silybum marianum seeds. This research was done to assess the protectiverole of silymarin against liver toxicity induced by DIC in male rats.Methods: Randomly, 40 male Wistar rats were assigned into five groups as follows: Group 1:control group, Group 2: DIC-only treated (50 mg/kg, i.p), Group 3: silymarin-only treated (200mg/kg, p.o); Groups 4 and 5: DIC (50 mg/kg, i.p) plus silymarin (100 mg/kg and 200 mg/kg, p.o,respectively) treated. Various biochemical, molecular, and histological parameters were evaluatedin serum and tissue.Results: In the DIC-only treated group, the levels of liver glutathione peroxidase (GPx), superoxidedismutase (SOD), intracellular glutathione (GSH) and catalase (CAT) significantly diminished andthe levels of total bilirubin, alkaline phosphatase (ALP), nitrite, alanine aminotransferase (ALT),malondialdehyde (MDA), serum tumor necrosis factor-α (TNF-α), aspartate aminotransferase(AST), and TNF-α gene expression were remarkably elevated relative to control animals. In otherhands, treatment with silymarin caused a noticeable elevation in GPx, SOD, GSH, CAT and aremarkable reduction in levels of total bilirubin, ALP, nitrite content, ALT, MDA, serum TNF-α,AST and TNF-α gene expression relative to DIC-only treated group. Histopathological injurieswere also improved by silymarin administration.Conclusion: The results confirm that silymarin has an ameliorative effect on liver toxicity inducedby DIC and oxidative stress in male rats.

The Impact

It is common for food to be made more palatable through the use of the flavour enhancer monosodium glutamate, also known as vetsin powder. The purpose of the study described in this paper was to explore how vetsin-induced hepatic toxicity, DNA fragmentation, damage, and oxidative stress modifications could be mitigated with moringa leaf extract (MLE). To that end, 40 male rats were separated into four groups: normal control, positive control or MLE, vetsin, and vetsin combined with MLE. Results indicated that, compared to the control group, the levels of serum alanine aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), liver malondialdehyde (MDA), DNA damage, injury, PCNA, and P53 expressions were significantly enhanced by the administration of vetsin (P<0.05). However, the vetsin group had significantly reduced levels of albumin, globulin, total protein, liver glutathione (GSH), superoxide dismutase enzyme (SOD), catalase, and glutathione S-transferase (GST) enzyme activities (P<0.05) by comparison to control. Meanwhile, modifications in liver functions, oxidative stress, DNA damage, liver injury, and PCNA expression were alleviated when vetsin was administered alongside MLE. The authors conclude that vetsin may have many side effects and that MLE can ameliorate biochemical changes, oxidative stress, hepatic injury, PCNA, and P53 alterations induced by vetsin administration.

Purpose: To determine the protective effect of puerarin against acute liver injury in septic rats, and the mechanism involved.Methods: Eighty-seven Sprague-Dawley (SD) rats were assigned to control, sepsis and puerarin groups (each having 29 rats). Serum levels of NF-kB, TNF-α, IL-1 β, IL-6, ALT and AST were assayed. Liver lesions and levels of NO, SOD, iNOS and malondialdehyde (MDA) were measured using standard procedures.Results: Compared with the control group, the levels of NF-kB, TNF-α, IL-1β, IL-6, AST, ALT, NO, MDA and iNOS significantly increased in the sepsis group, while SOD level decreased significantly. In contrast, there were marked decreases in NF-kB, TNF-α, IL-1β, AST, ALT, NO, MDA and iNOS in puerarin group, relative to the sepsis group, while SOD expression level was significantly increased (p <0.05). The level of p-p38 in liver of septic rats was up-regulated, relative to control rats, while Nrf2 significantly decreased (p < 0.05). The expression level of p-p38 in the puerarin group was significantly decreased, relative to the sepsis group, while the expression level of Nrf2 significantly increased (p < 0.05).Conclusion: Puerarin mitigates acute liver injury in septic rats by inhibiting NF-kB and p38 signaling pathway, down-regulating proinflammatory factors, and suppressing oxidative stress. Thus, puerarin may be developed for use in the treatment liver injury.

Bisphenol A (BPA) is used to produce polycarbonate plastic and epoxy resins which are used in many consumer products. Most people encounter BPA in their daily routines. However, it has been heavily reported that BPA has a neurotoxic effect. The present study aimed to investigate the effect of lycopene on cognitive deficits induced by a high dose of BPA focusing on mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway, oxidative stress, apoptosis, and memory retrieval in adult male rats. Therefore, 72 rats were divided into four groups: control group, BPA group (50 mg/kg body weight (bw)) 3 days a week for 42 days, lycopene group (10 mg/kg bw) daily for 42 days, and lycopene + BPA group. Concurrent treatment of lycopene with BPA improved the learning and cognition memory in Morris water maze and novel object recognition tests along with an increase in acetylcholine esterase activity as well as inhibition of oxidative stress by restoring reduced glutathione and suppressing malondialdehyde hippocampal level to their normal levels. Mechanistically, lycopene upregulated the protein expression of tyrosine receptor kinase B, which resulted in an upsurge in its downstream cascades MAPK/ERK1/2/cAMP response element-binding protein (CREB)/brain-derived neurotrophic factor (BDNF) signaling pathway in the hippocampus of BPA-intoxicated rats. Furthermore, concurrent treatment of lycopene with BPA prevented apoptosis by marked decrease in Bcl-2 associated X protein (Bax) gene expression and caspase 3 activity while restoring B-cell leukemia/lymphoma-2 (Bcl-2) gene expression. In conclusion, the present study provided evidence that lycopene exerted a neuroprotective effect against BPA intoxication in hippocampi of rats via its antioxidant properties, activation of MAPK/ERK pathway, and inhibiting a neuronal apoptosis which reflected on improving the learning and cognition memory.

Arsenic (As) poisoning is widespread due to exposure to pollution. The toxic level of (As) causes oxidative stress-induced aging and tissue damage. Since melatonin (MLT) has anti-oxidant and anti-aging properties, we aimed to evaluate the protective effect of MLT against the toxicity of sodium arsenite (NaAsO2). Healthy male NMRI mice were divided into eight different groups. The control group received a standard regular diet. Other groups were treated with varying diets, including MLT alone, NaAsO2, and NaAsO2 plus MLT. After one month of treatment, biochemical and pathological tests were performed on blood, heart, and lung tissue samples. NaAsO2 increased the levels of TNF-α, 8-hydroxy-2-deoxy guanosine (8OHdG), malondialdehyde (MDA), reactive oxygen species (ROS), and high mobility group box 1 (HMGB1), increased the expression of TNF receptor type 1-associated death domain (TRADD) mRNA and telomerase reverse transcriptase, and decreased the expression of Klotho (KL) mRNA in both plasma and tissues. In contrast, MLT reduced MDA, ROS, HMGB1, lactate, and TNF-α enhanced the mRNA expression of KL, and suppressed the mRNA expression of the TERT and TRADD genes. Thus, MLT confers potent protection against NaAsO2- induced tissue injury and oxidative stress.

Gastric ulcer is a serious health problem that affects more than 10% of the World's population. Aspirin is the most common drug causes gastric ulcer also, most of the ulcer drugs have harmful side effects, so studies have focused on finding an alternative natural solution. This work provides a natural solution to protect the gut against ulcers, especially aspirin, by using a diet supplemented with pomegranate peel powder in rats. Levels of active components in pomegranate peel powder were detected using the certified methods. For the biological evaluation, 21 male rats (weight, 140-170 g) were used in three groups, group (1) is a control, group (2) ulcer group, and group(3) (ulcer supplemented group). The duration of the evaluation was 4 weeks. Gastric ulcer was produced by aspirin water suspension (500 mg/kg rat weight). The gene expression of cyclooxygenase-2 (COX-2) and tumor necrosis factor (TNF-α) were determined by RT-PCR. Pomegranate peel powder (10 % w/w) reduced the gastric ulcer area and ulcer index, gastric juice volume, and acidity. Pomegranate powder recovers gastric mucus content and gastric tissue at the histological level. Plasma nitric oxide production was raised while plasma TNF-α level was diminutive by pomegranate peel powder. The gastric mucosal TNF-α and COX-2 gene expression were significantly (p≤ 0.05) down-regulated (2.4 and 12.5 fold-change, respectively) using the pomegranate peel powder. This study introduces pomegranate peel powder (10%) as a protective food supplement against gastric ulcers.

Background and Objective: Mercury is one of the most harmful heavy metals and its toxicity causes severe multi-organ dysfunction. This study was designed to explore novel molecular pathways involved in the hepatoprotective effect of vitamin E (Vit-E) and Lactobacillius plantarum (Lac-B) against mercury toxicity.[Formula: see text] Method: Acute hepatotoxicity was induced by administration of high dose of mercuric chloride (HgCl2) in male rats, Vit-E or/and Lac-B were given along with HgCl2 for 2 weeks. The effects of those antioxidants were studied focusing on their anti-apoptotic, anti-oxidative stress and anti-inflammatory eficacies. Histopathological examinations were also conducted. Results: The administration of HgCl2 induced liver injury which manifested by elevation in serum ALT and AST. Liver MDA, caspase-3 and TNF-α levels were markedly increased; whereas, GSH level and SOD activity were declined. HgCl2 significantly elevated the expressions of hepatic CHOP, GPR87, NF-κB and mTOR. Histopathological examination revealed massive hepatocyte degeneration following HgCl2 administration. Treatment with Vit-E or/and Lac-B restored the normal levels of the previously mentioned parameters, as well as improved hepatic architecture. Conclusion: Vit-E and Lac-B provided protective effect against HgCl2-induced hepatotoxicity via reduction of oxidative stress and inflammation, and downregulation of CHOP, GPR87, NF-κB and mTOR proteins’ expressions.
